Subject: [PATCH 18/19] sh: Don't need to cast parameter of ascii_is* to
 (unsigned char).

Our replacements for these functions are not undefined for negative
values.

Thanks: Eric Blake
Fixes: commit 9f34db74786fdc92b290a7d47e4b003bd84fec69.
(cherry picked from commit 06a79b8bb8cfd97a272223c967601d8858acb817)
